GYPBIAN KORDEK AND JOSEPH KORDEK, OF PHILADELPHIA, PENNSYLVANIA.

TROLLEY.

Specification of Letters Patent.

Application filed September 1, 1911.

Patented Dec. 5, 1911.

Serial No. 647,135.

To all whom it may concern:

Be it known that we, CYPRIAN KORDEK and JosEPn KoRoEK, subjects of theEmperor of Austria-Hungary, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Trolleys, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to trolleys, and the objects of our inventionare, first, to furnish a trolley pole or harp with simple and effectivemeans, in a manner as will be hereinafter set forth, for preventing atrolley wheel from becoming accidentally displaced from a trolley wire;second, to furnish a trolley harp with guards that will not interferewith the overhead construction of an electric trolley railway system;and third, to provide a trolley attachment that is strong, durable andapplicable to various types of poles and harps.

We attain the above objects by a mechanical construction that will behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein- Figure 1 is a sideelevation of a trolley in accordance with this invention; Fig. 2 is atop plan of the same, and Fig. 3 is a bottom plan of a portion of thetrolley.

The reference numeral 1 denotes a portion of a trolley pole, having aharp 2 provided with a journal pin or spindle 3 for a revoluble trolleywheel 4 adapted to travel against an electric conductor or trolley wire5. The under side of the pole 1, contiguous to the harp 2, is providedwith a rightangularly disposed pin 6, and movably mounted upon this pinare inwardly projecting apertured bearings 7 of curved arms 8. Theinwardly projecting bearings 7 are retained upon the pin 6 by a washer 9and a cotter pin 10. The curved arms 8 have downwardly flared extensions11 terminating in eyes 12 to which are connected cables or ropes 13.These cables or ropes can terminate in a single trolley rope adapted tobe manipulated by a conductor or operator of a car when it is desired toopen or spread apart the arms 8. The curved arms 8 are flared outwardly,as at 14, and they extend upwardly at the sides of the trolley Wheel 4,to a point above the harp 2. At this point the arms are bent forwardlyand inwardly, as at 15, then upwardly to provide yokes 16, and thenforwardly again, as at 17. These forwardly extending ends of the armsfacilitate the trolley attachment in entering and passing under atrolley wire frog or guard rail.

Revolubly mounted upon the yokes 16 are rollers 18 that extend inproximity to each other, and at a point above the trolley wire 5. Theserollers are adapted to prevent displacement of the trolley wheel 4relatively to the wire 5. The curved arms 8, at a point below the harp 2are connected by a coiled retractile spring 19 adapted to normallymaintain the rollers in proximity to each other.

The cables 13 are connected in a manner whereby the upper end of thearms 8 can be swung apart to permit of the trolley wheel 4 being quicklyremoved or placed upon the trolley wheel 5.

The trolley attachment in its entirety can be made of light and durablemetal, and of various sizes.

What we claim is:

The combination with a trolley pole, a harp carried thereby, and a wheelrevolubly supported by said harp and adapted to travel against a trolleywire, of a pin carried by said pole adjacent to said harp, curved armshaving inwardly projecting bearings loosely mounted upon said pin, saidarms having depending flared extensions terminating in eyes adapted tobe connected to cables, said curved arms having the upper ends thereofbent forwardly and Copies of this patent may be obtained for five centseach, by addressing the commissioner of ratents,

Washington, .D. 0.
